Compilation − The source code in python is saved as a .py file which is then compiled into a format known as byte code, byte code is then converted to machine code. After the compilation, the code is stored in .pyc files and is regenerated when the source is updated. This process is known as compilation. Linking − Linking is the final phase where all the functions are linked with their definitions as the linker knows where all these functions are implemented. This process is known as linking. image compilation.jpg----- Note − Python programs are both compiled as well as ... Read More
What is an iterable? An iterable can be loosely defined as an object which would generate an iterator when passed to inbuilt method iter(). There are a couple of conditions, for an object to be iterable, the object of the class needs to define two instance method: __len__ and __getitem__. An object which fulfills these conditions when passed to method iter() would generate an iterator. Iterators Iterators are defined as an object that counts iteration via an internal state variable. The variable, in this case, is NOT set to zero when the iteration crosses the last item, instead, StopIteration() is ... Read More
In Python, to get values from users, use the input(). This works the same as scanf() in C language. Input multiple values from a user in a single line using input() To input multiple values in one line, use the input() method − x, y, z = input(), input(), input() Let’s say the user entered 5, 10, 15. Now, you can display them one by one − print(x) print(y) print(z) Output 5 10 15 From above output, you can see, we are able to give values to three variables in one line. To avoid using multiple input() methods(depends on ... Read More
We are going to cover some useful python tricks and tips that will come handy when you are writing program in competitive programming or for your company as they reduce the code and optimized execution. Get n largest elements in a list using the module heapq Example import heapq marks = [91, 67, 34, 56, 78, 99, 87, 23, 78, 66] print("Marks = ", marks) print("Largest =", heapq.nlargest(2, marks)) Output Marks = [91, 67, 34, 56, 78, 99, 87, 23, 78, 66] Largest = [99, 91] Get n smallest elements in a list using the ...

YouTube is truly incredible! I had a YouTube video that was almost an hour long. The other day, I wanted to share it with my friends, but the problem was that the part of the video that would be of interest to my audience begins after 20 minutes and 10 seconds. I wanted to share the video in such a way that, it would begin playing at this particular moment. I didn't want my friends to watch the first 20 minutes of meaningless video and then forward it to a specific time. Of course, if you own the video, you ... Read More

In this example, we will count Negative Numbers in a Column-Wise and Row-Wise Sorted Matrix. At first, we will create a matrix − mat = [ [-1, 3, 5, 7], [-6, -3, 1, 4], [-5, -1, -10, 12] ] Pass the matrix to a custom function and use nested for loop − def negativeFunc(mat, r, c): count = 0 for i in range(r): for j in range(c): if mat[i][j]
You're in for a threat if you're aspiring to be a YouTube influencer and you want to know about the world of brand and blogger collaborations. A brand collaboration is when a content creator is paid by a brand to produce content using the brand's merchandise.

This comes under Brand Collaboration and they pay money for reviewing such products.And the product links will be provided in the ... Read More
Yes, Python supports polymorphism. The word polymorphism means having many forms. Polymorphism is an important feature of class definition in Python that is utilised when you have commonly named methods across classes or sub classes. Polymorphism can be carried out through inheritance, with sub classes making use of base class methods or overriding them. There are two types of polymorphism Overloading Overriding Overloading Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding Overriding means having two methods with the same method name and parameters (i.e., method signature). One ... Read More
Yes, Python supports multiple inheritance. Like C++, a class can be derived from more than one base classes in Python. This is called Multiple Inheritance. In multiple inheritance, the features of all the base classes are inherited into the derived class. Let us see the syntax − Syntax Class Base1: Body of the class Class Base2: Body of the class Class Base3: Body of the class . . . Class BaseN: Body of the class Class Derived(Base1, Base2, Base3, … , BaseN): Body of the class The Derived class inherits from both Base1, Base2 and Base3classes. ... Read More
